Over time, you may experience some issues with your smartphone battery.Because batteries are consumables, their performance will degrade over time.After a few years, they won't hold as much charge as they did when they were new.
Knowing this, you probably want to preserve the health of your phone battery as much as possible.We'll show you how to check and monitor your Android's battery health to keep your device running smoothly for as long as possible.
The Best Way to Monitor Battery Health on Android: AccuBattery
AccuBattery is one of the best rated Android apps that provides a lot of information about your Android device's battery.While it doesn't provide as much data as a root-only app, it's the best battery health checker for non-root Android users.
After installing AccuBattery, you'll see an introductory screen with some information on how the app works.
The basic idea behind keeping an eye on your Android's battery health is that your phone's battery has a finite number of charge cycles before its performance degrades significantly.A full cycle occurs every time the battery completes a full discharge from 100% to 0%.It doesn't have to be a one-off, though.
As an example, let's say your phone drains from 100% to 50%.If you then charge it up to 100% and then let it drop down to 50% again, that's equivalent to a full cycle.
AccuBattery says that if you only charge your device to 80 percent instead of 100 percent, you'll use fewer cycles, extending the life of your battery.It gives you tools to help you change your smartphone charging habits to improve battery life.

How to Check Your Android's Battery Health with AccuBattery
After the initial setup, you can browse AccuBattery's tabs, but they don't have much information yet.Due to the nature of the app, you'll need to let it install and use your phone as you normally would for a while before you start getting useful information.
To start, your goal should be to unplug your phone when it hits 80 percent charge. AccuBattery includes an alarm that will alert you at this charge level.If you want to tweak it, visit the Charging tab and drag the blue slider to a different level.
When your phone is plugged in, the tab will also display information about how long it takes to charge.Over time, as it becomes more accurate, this will help you estimate how long your phone needs to sit on the charger to reach your desired charge level.
Monitor Which Android Apps Use Battery
On the Power tab, you'll find information about how your phone uses power.It shows how much battery is being used when your screen is on and off, and in deep sleep.
Under App Usage Permissions, make sure to grant the app permission to access usage data.This can give you more insight into which apps are draining your battery the most.
As the app learns how you use your phone, you'll see a time estimate of how long the battery will last at your current charge level.
AccuBattery's battery health data
Of course, this information is all about how to monitor your Android phone's battery health.The Health tab displays your battery health statistics by comparing your battery's current estimated capacity to the factory design capacity.This enables you to see how much power your battery has on a full charge, compared to how it was when it was brand new.
For more insight, you can check out the battery wear graph below.This shows how much stress you're putting on your battery each day, so you can learn about your habits and make changes if needed.
If you want to see stats from previous days, take a look at the History tab.Click on an entry to view more information.
AccuBattery options and professional upgrades
That's everything you need to know about monitoring your Android device's battery health with AccuBattery.Before you finish setting it up, you should check out a few of its preferences to make sure the app is behaving the way you like it.Click the three-dot menu button in the upper right corner and select "Settings" to view it.
Among the options, you can change the temperature units, set a do-not-disturb time for charging alarms, and change the app's notification options.By default, AccuBattery displays a persistent notification with some battery information.If you find this annoying, you can disable it.
If you like the app, you should also consider purchasing AccuBattery Pro as an in-app purchase.For a few bucks, you can get rid of ads, get access to a dark theme, plus see more historical stats and include extra battery information in notifications.
Can you check battery health naturally on Android?
We recommend AccuBattery for most people, but if you don't want to use it for some reason, you might wonder if this battery health information is available without the app.Unfortunately, Android doesn't provide a built-in way to check battery health on all devices.In case you didn't know, Android does provide some basic battery information in its settings menu.
To take a look, visit Settings > Battery, tap the three-dot menu in the upper right.In the menu that appears, tap Battery usage.This may vary slightly, depending on your Android phone and version (on original Android 13, the battery usage option is in the main options list).
On the screen that appears, you'll see a list of apps draining the most battery since your device was last fully charged.For full details, tap the three-dot menu button in the upper right and select Show full device usage, including usage by system processes such as the screen and the operating system itself.This may appear at the bottom of the list, depending on your phone.
While this won't let you manage your Android's battery health, you can at least identify apps that are using too much battery and curb their use.In turn, this will keep your battery at its powerful capacity for longer.
How to Check the Battery Health of Your Samsung Device
If you have a Samsung phone, you can take advantage of a built-in menu to check the device's battery health.To do this, if you haven't already, install the Samsung Members app from Google Play or the Galaxy Store.Then open the app, tap "Get Help" at the bottom, and select "Enter Phone Care."Finally, select Interactive Inspection, then Battery.
You'll see the battery level, which is the current charge level.Life is the general health of your battery, while capacity is how much power your battery can store.If you don't see "Good" next to "Life," it may be time to consider replacing the battery.
Review Android Battery Health with Dial Codes
Android has some hidden codes that you can enter in your phone app to access the test menu.One of them displays various information about your device, including its battery health.To see it, open the dialer and enter *#*#4636#*#*.
Unfortunately, in our tests with the Pixel 13 running Android 4, this menu didn't include any battery data.However, you may have better results on your device.Some phones will have a battery info menu showing good or other health ratings.
This is the only battery data provided by Android itself.But keep in mind that you can observe many signs of battery drain yourself.If your phone drains quickly when you're not using it, or just doesn't last until the end, the battery may be dead.
Easy Android Battery Health Check
AccuBattery gives you easy access to the health of your Android battery.While it's not perfect, it's a lot more informative than Android itself can provide.Be patient and wait a week or two after installing the app, and you'll have actionable data to apply.
Remember, you don't have to stress too much about your battery health.Unless you're constantly draining your battery, or running it under intense conditions like extreme heat, most phone batteries are strong enough to last several years of normal use.It's not a bad idea to preserve battery health as much as possible, but you shouldn't get overly obsessed with it either.
